Two rounds of interviews, no HR only technical, the second round was live coding since I'm in Berlin i went to their offices for this they also asked more technical questions before the challenge began, it was a mock viewmodel handling some flows inside, pretty straight forward. Th whole process was very fair, i could have succeed if i didn't chose the office option since it made me really nervous, so it was my mistake.
Overall a very nice experience, they sent me a very through feedback that helped me a lot, so they are not one of those companies that ghost you after rejection without any feedback.
The position got filled shortly after that, and everyone at the company were there for some years so job opening wont last long here, i can only imagine why, its such a nice and respectful company.
